Power allocation method and terminal device

A terminal device, comprising:

• a processor and a memory, wherein the memory is configured to store a computer program, and the processor is configured to call and run the computer program stored in the memory to execute operations of:
• determining total transmit power at a first transmission occasion, the total transmit power being a sum of transmit power for a plurality of signals to be transmitted, the plurality of signals to be transmitted at least comprising a first signal, the first signal being a message (Msg) A in a 2-step random access process, and the first signal comprising at least one of a Physical Uplink Shared Channel (PUSCH) in the 2-step random access process or Physical Random Access Channel (PRACH) in the 2-step random access process, wherein
• responsive to that the total transmit power is higher than maximum transmit power of the terminal device, the processor is further configured to determine actual transmit power for the first signal according to at least one of a type of a cell for transmitting the first signal or a channel type of the first signal as well as a power allocation priority order, the power allocation priority order comprising an order of power allocation priorities of the first signal and other signals except the first signal,
• wherein responsive to that the actual transmit power for the first signal is determined by the terminal device according to the channel type of the first signal and the power allocation priority order, the PRACH and PUSCH comprised in the first signal have different power allocation priorities, and
• wherein in the power allocation priority order, at least one of a power allocation priority of the PRACH or a power allocation priority of the PUSCH comprised in the first signal on a Primary Cell (PCell) is higher than at least one of:
• a power allocation priority of Physical Uplink Control Channel (PUCCH) transmission with at least one of Hybrid Automatic Repeat reQuest Acknowledgement (HARQ-ACK) information or Scheduling Request (SR) or a power allocation priority of PUSCH transmission with HARQ-ACK information;
• a power allocation priority of PUCCH transmission with Channel State Information (CSI) or a power allocation priority of PUSCH transmission with CSI;
• a power allocation priority of PUSCH transmission without HARQ-ACK information or a power allocation priority of PUSCH transmission without CSI;
• or
• a power allocation priority of a Sounding Reference Signal (SRS) or the power allocation priority of the PRACH in the 4-step random access process on a non-PCell.

A non-transitory computer-readable storage medium, configured to store a computer program, the computer program enabling a computer to execute operations of:

• determining, by a terminal device, total transmit power at a first transmission occasion, the total transmit power being a sum of transmit power for a plurality of signals to be transmitted, the plurality of signals to be transmitted at least comprising a first signal, the first signal being a message (Msg) A in a 2-step random access process, and the first signal comprising at least one of a Physical Uplink Shared Channel (PUSCH) in the 2-step random access process or Physical Random Access Channel (PRACH) in the 2-step random access process;
• and
• responsive to that the total transmit power is higher than maximum transmit power of the terminal device, determining, by the terminal device, actual transmit power for the first signal according to at least one of a type of a cell for transmitting the first signal or a channel type of the first signal as well as a power allocation priority order, the power allocation priority order comprising an order of power allocation priorities of the first signal and other signals except the first signal,
• wherein responsive to that the actual transmit power for the first signal is determined by the terminal device according to the channel type of the first signal and the power allocation priority order, the PRACH and PUSCH comprised in the first signal have different power allocation priorities, and
• wherein in the power allocation priority order, at least one of a power allocation priority of the PRACH or a power allocation priority of the PUSCH comprised in the first signal on a Primary Cell (PCell) is higher than at least one of:
• a power allocation priority of Physical Uplink Control Channel (PUCCH) transmission with at least one of Hybrid Automatic Repeat reQuest Acknowledgement (HARQ-ACK) information or Scheduling Request (SR) or a power allocation priority of PUSCH transmission with HARQ-ACK information;
• a power allocation priority of PUCCH transmission with Channel State Information (CSI) or a power allocation priority of PUSCH transmission with CSI;
• a power allocation priority of PUSCH transmission without HARQ-ACK information or a power allocation priority of PUSCH transmission without CSI;
• or
• a power allocation priority of a Sounding Reference Signal (SRS) or the power allocation priority of the PRACH in the 4-step random access process on a non-PCell.
